[Plugin: Conference Schedule] Session admin – date/time fields disappeared

For what it’s worth, the session date/time admin problem is with WordPress 3.3 — it works as intended with 3.2

I am a WordPress newbie, but It appears this problem is due to the way add_meta_box is being done. For version 0.5.2 conference-schedule.php on line 84 there is the line:

$this->add_meta_box( 'cs_schedule_metabox', __( 'Schedule', $this->name ), 'schedule_metabox', 'session', 'normal', 'core' );

Take that line and move it to the admin_init function on line 278. Then it will show up again. At least it does for me.

I think this is related to this issue: https://wpdevel.wordpress.com/2011/12/07/do-not-include-wp-adminincludestemplate-php-to-get-add_meta_box/

Indeed… that fixes the problem.

Many thanks for taking the time to research and resolve it!

Thank you for sharing this fix! It worked for me on two different sites.
